I too have "waited, waited for the LORD." I wonder how John felt, day after day, waiting for the one he did not know. Or Paul, waiting for word that his letters had found "ears open to obedience". Did Isaiah know that God would wait generations before fulfilling the song they had placed in his mouth? Did he care? The servant works on the master's timeline, not her own. So we wait. Because that is our delight, however frustrating it may be. "Here am I, Lord; I come to do your will."
